(Cl. 29-207)The present invention relates to a device for separating travellersarranged in a row on a guide rod or rail and for pushing the separatedtravellers onto the rings of ring spinning and/or ring doubling frames.

In the known devices of this kind, the travellers arranged in a row on aguide rail are directly pressed by a compression spring against av stop,which is adjustably fixed on the casing of the device so that it can beset to suit travellers having different widths; `The separating andpushing `of the foremost traveller which is pressed against the stop, iseffected in the known devices by a tongue which can be shifted orswivelled and is moved in Vthe gap between the stop and the guide rail.Since the tongue in the known devices may not be wider than the gapbetween the stop and the guide rail, which corresponds to the width ofthe travellers to be installed, it is necessary to replace the tonguewhenever the device is to be used with travellers of a different width,and this is really very troublesome. Further, in the existing devices,the bearing means of the tongue is constructed in such a way thatneither lateral deviation of the tongue,

separating the foremost traveller and pushing the latter i onto thering.

Another advantage of the device embodying the invention resides in thefact that, when the traveller is being pushed onto the ring, the tongueat first moves yalong 'a straight line until the open ends of thetraveller thereby rolled onto have engaged over the usual T-shapedprojection of the ring, and thereafter the forward end of the tonguemoves along a curve, an inclined plane, or the like in the upwardlyinclined direction, so that the traveller is the ring. Such movement ofthe tongue effects rotation through 90 of the traveller made of hardsteel wire, and absolutely excludes the possibility of breakage of thetraveller or `any other mishap, even when the finest travellers arebeing pressed onto the ring. Since a traveller inserting device isespecially valuable when replenishment of the stock of travellers can bein the accompanying drawing, where:

nor alteration in the direction of motion thereof, is pos- 1 sible whenpushing the travellers onto a ring. These existing devices also fail toprovide any means for holding, in an inoperative position, thecompression spring which normally urges the stack of travellers againstthe stop so that the supply of travellers on the guide rail can bereplenished. In the known devices the foremost of the stacked travellersis only held firmly by being pressed against the stop, and no means areprovided for otherwise determining the position of the travelleraccurately before the latter is pushed onto a ring.

The object of the present invention is to provide a device for insertingthe travellers, which is very handy, light and easy to manipulate, andwhich also offers the advantage that a great range of different sizes oftravellers can be inserted with one device without requiring thechanging of any parts thereof.

According .to the invention, this object is accomplished by mounting thestop on the movable tongue so that the stop can be shifted transverse tothe direction of movement of the tongue. With this arrangement, thetongue can have the thickness needed for the greatest width of travellerto be installed therewith. At any time, the movably arranged stop coversthe superuous width of the tongue, so that the only part of the width ofthe tongue which is yleft free to act on the traveller is thatcorresponding exactly to the Width of the traveller. Since the stop ismounted on the tongue, it is also possible to'mount the tongueresiliently for permitting deviation of the latter in the direction ofthe guide rail, so that the stop can be set a distancevfrom the end ofthe guide railwlich is smaller than the width of the traveller to beinstalled and the foremost traveller is still engaged and accuratelylocated by the guide rail while waiting to be pushed onto a ring, andthe tongue is laterally deflected, along with the stop, duringritsmovement for effected quickly, certainly and very simply, the deviceembodying the invention has a pressure-piece which is loaded with a,spring and carried on a slide rail arranged parallel to the travellerguide rail, to normally act upon the stack of travellers on the latterwith'the pressure-piece being retractable to a stop and there free to beturned outof the range of the guide rail so that an additional stack oftravellers can be installed on the guide rail. In this position thepressure-piece is held firmly by a notch, so that it is possible toinstall the new travellers, without having to remove parts of thedevice. v

Referring initially to Figs. l-5, it can be seen that, between twohandle parts 1 and 2, there is secured a plate 3 which projects, at itsfront end, out of the handle 1, 2. The plate 3 forms a rigid element andhas a recess .4 which `can beset onto the edge of the ring 5 of a ringspinning frame, as illustrated in Figs. l, 6, 7 and 8. At one side ofplate 3 there is a slider 7 `forming a movable element and having aforked end projecting out of the handle 1, 2. An operating handle 9 ispivotally mounted on a pin 8 in the handle 1, 2 and. has a roundedextension 10 engaging in a slot 11 inthe slider 7. With one hand thehandle 1, 2 can easily be held and the operating handle 9 simultaneouslypressed towards it, so that the slider 7 is pushed towarlifthe forcarrying a stock ofV front. A spring 12 always tends to return slider 7to its position of rest, as is illustrated in Fig. 1.

At the front end of the plate 3 a pipe 14 is xed above the recess 4 bymeans of a screw 13 (Figs: 2 and 8), and a sleeve 15 is longitudinallydisplaceable on the pipe 14. A screw 17 extends through a longitudinalslit 16 provided in the pipe 14 (see Fig. 9), and connects the sleeve 15to a sliding block 18, which is displaceable within the pipe and againstwhich one end of a compression spring 19 acts. The other end of spring19 abuts against the closing screw 20 at the end of the pipe remote fromplate 3 (Figs. 1 and 2). Thus the sleeve 15 is constantly forced towardthe plate 3 by means of the spring 19. A stock of travellers 21 (Figs.6, 7 and 8) is pushed-on a guide rod 22, which extends parallel to pipe14 and is rigidly connected by means of a strap 23 to the pipe 14 andthus to the plate 3. The row of travellers 21 forming the stock isspring-loaded, in that the sleeve 15 has a lug 24 (Figs. 1,3 and 10),formed with an opening adapted to receive the guide rod 22 and normallypressing against the traveller 21 furthest from plate 3. In order thatthe sleeve 15 along with the lug 24 can slide past the strap 23, thesleeve and the lug are provided with slits through. which the strap 23can pass (Figs. 1, 3 and 10). The foremost traveller 21 bears against astop 25 carried by the forked end of the slider 7, the stop 25 beingtransversely adjustable relative to the direction of movement of theslider 7 so that the distance from the end 26 of the rod 22 to the stop25 can be varied to suit the width of the travellers 21. The adjustablemounting for the stop 25 includes a screw 27 which is rotatably carriedby the forked end of slider 7 and secured against axial displacement bya pin 29 engaging tangentially in a groove 28. The screw 27 extendsthreadedly through stop 25 and the end of screw 27 has a plurality ofmilled notches 30, for engagement by a spring loaded detent ball 30adisposed in a small bore running radially to the screw, so that one canonly turn the screw by overcoming a certain resistance exercised by theball. In this way, inadvertent displacing of the stop 25 is prevented.

The end 26 of the guide rod 22 projects beyond the plane of the slidingcontact of the plate 3 and of the slider 7 into the gap between plate 3and stop 25 by a distance equal to a fraction of the width of that gapin order to prevent the foremost traveller lying against stop 25 frominadvertently falling out through this gap. However, in order to avoidobstruction of the displacing movement of the slider 7 by the end 26 ofthe guide rod 22 projecting into the gap, the slider 7 is pressedresiliently against the plate 3 by means of a leaf-spring 31 (see Fig.5), and the end 26 of the guide rod 22 is chamfered. Thus, when theslider is moved forwardly, the front end of the slider 7 is deflectedlaterally, and rides across the projecting end 26 of rod 22. The lateraldeflection of slider 7 away from plate 3 increases the gap between stop25 and end 26 of rod 22, so that a traveller can be pushed therebetween.

In order to facilitate the pressing of the travellers 21 onto the ringof the ring spinning frame, the front end of the slider 7 is made tomove upwardly during a nal portion of its forward movement with atraveller being pushed in front of the slider, as can be seen in Fig. 7.In this manner the front end of the slider is made to deviate from astraight-line movement, so that it elects the necessary quarter turn tobe made by the traveller about its axis during installation on the ring5, and thus it is possible to install even quite fine travellers whichwould be pressed out of shape if the slider moved only in a straightline. It is advantageous for the slider 7 to have a small projection 31a(Figs. 6 and 7) in order to achieve the desired upward pressing of thetraveller. This upwards movement of the end of the slider is caused by apin 32 which is fitted on the front portion of the slider 7 (Figs. l, 5,6 and 7) and'is guided in a curved guideway 33 machined in the plate 3.A second pin 34, arranged beside the slot 11 on the slider 7,reciprocates in a straight guideway 33a (shown in broken lines on Fig.l) in the plate 3, so that during its forwards and backwards movementthe slider 7 undergoes a small tilting movement round this second pin34.

The position of rest of the slider 7 can be adjusted by turning aneccentric pin 35 (Fig. l) which is rotatably mounted -in handle 1, 2 andis engageable by the back end of the slider. It is thus possible toadjust the rest position of slider 7 so that the traveller 21 lyingagainst the stop 25 is situated at only quite a small distance away fromthe front end of the slider and thus, without being turned in any way,is from the beginning of the moment of the slider pushed with itsopening opposite to the edge of the ring 5. If, for example, thicker orthinner travellers have to be brought onto the ring spinning frame, theposition of rest of the slider can be correspondingly adjusted byturning the eccentric 35. If the new travellers are at the same timewider or narrower, the stop 25 is then also adjusted by means of thescrew 27. Because of this possibility of adjustment, about thirtydifferent sizes of travellers can be inserted. The smallest width of thetravellers may, for instance, amount to 0.40 mm., and the greatest widthmay amount to about 2.6 mm.

Another possibility of adjusting the device to accommodate differenttravellers is shown in Figs. 13 to 15 in which the guideway 33 in theplate 3 is replaced by a guideway 46 in an intermediate plate 45. Theintermediate plate 45 is arranged between the handle part 1 and theplate 3, and has two oblong holes 47, through which pass two screws 48,by means of which the intermediate plate 45 can be rmly clamped betweenthe plate 3 and the handle part '1. An opening 49 is formed in the plate3, yso that the pin 32 xed on the slider 7 can extend through opening 49to engage in the guideway 46 in the intermediate plate, while the pin 34only reaches into a horizontal oblong hole 50 in the plate 3.

If the screws 48 are slightly loosened, the intermediate plate 4'5 canbe displaced longitudinally through a distance determined by the lengthof the hole 47, such displacement being eiected by turning an elementhaving an eccentric middle portion 51 located in an opening 52 in theintermediate plate 45, and opposite end portions 53 which are seatedrotatable in holes in the plate 3 and in the handle part 1 respectively.Since the spring 12 tends to pull the slider 7 and also, through the pin32, the intermediate plate 45, to the right, as viewed in Figs. 13 and14, the turning of the eccentric 51 produces a reciprocating movement ofthe intermediate plate 45. In this manner the guide way 46 can be movedtoward or away from the stock of travellers on the guide rod (not shown)so that, when the slider 7 presses a traveller onto the ring 5, themovement of the front end of the slider along an inclined path occursnearer to, or further away from, the ring 5. It is thus possible to suitthe device very iinely to travellers of different size. After theintermediate plate 45 has been adjusted, the screws 48 are tightenedagain, so that the intermediate plate 45 is held immovable.

If the stock of travellers on the guide rod 22 is exhausted, or iftravellers of another size have to be inserted, the sleeve 15 is drawnto its position most remote from the plate 3 and is locked there byturning the sleeve about pipe 14 so that the screw 17 enters a notch 36at the end of the slit 16 (Fig. 3). The effect of this manipulation isto bring the lug 24 of the sleeve 15 behind the rear end of the guiderod 22 and to swing it out laterally, as can be seen in Fig. l0. Thusnew travellers 21 can be pushed over the rear end of the guide rod 22.IPreferably this new stock of travellers consists of an orderly row oftravellers that can be pushed onto the free rear end of the guide rodand is held together by some means that can be destroyed. Such means canbe an adhesive essais strip running along the stack of travellers Aandtorn away from the latter after the travellers have been pushed onto theguide rod 22. Another destructible means for holding together the stackof travellers may be an adhesive which holds the travellers togetheronly so strongly that they can be detached singly from the stock oftravellers by the slider 7 when the operating handle 9 is drawn towardsthe handle parts 1, 2. After the destructible means has been removed, itis important that no remainder of it be left sticking to thetravellers.'

When stacksnof travellers are employed that are held together by aLwrapping of paper or a foil of synthetic material it is preferable toarrange at the free end of the guide rod 22 a small knife 44 (Fig. 3),which cuts the wrapping Vwhile the travellers are being pushed onto theguide rod.

In Fig. l2 another embodiment of the invention is illustrated in which,instead of the guide rod 22, a twopart traveller guide is providedhaving a rear part 37 which is detachably held between a front part 38and -a holder 39. When it is necessary to replenish the stock oftravellers, the part '37 can be changed for another identical partserving as a magazine and on which a stock of travellers has alreadybeen arranged. The holder 39 can be pushed to the rear for a short`distance along pipe 14, so that the part 37 can easily be introducedbetween the ends 4i) of holder 39 and front part 38 or withdrawn frombetween them. The front part 38 is connected to the pipe 14 through thestrap 43. Also in this embodiment, a spring-loaded sleeve `41 is movablealong pipe 14 and has a lug y42 pressing against the rearmost travellerin order to force the stock of travellers continually toward the plate3. The user can either keep several parts 37 serving as magazines withtravellers arranged in rows on them for use with the embodiment of Fig.12, or stacks of travellers which are held together by a destructiblemeans can be stored for installation on the guide rod 22 of the iirstdescribed embodiment of the invention. In both embodiments the stock oftravellers can be seen `at any time, so that the stock can bereplenished before it is completely exhausted.

Because of the fact that, in the described device, the slider 7 slidesalong close to the plate 3 and beyond the end 26 of the guide rod 22 orof the part 38, and that by simply turning the screw 27 the stop 25 canbe adjusted over a wide range in accordance with the width of thetravellers, the `device is adoptable for travellers of very differentsizes, without requiring the replacement of any parts. Only wheninstalling very small or very large travellers will it be desirable touse another traveller guide 22, or 37, 38 respectively. The changing ofthese parts is eifected by loosening the screw 13, `after which the pipe14 can be removed, together with all other parts attached to it.
